SPECIFICATION foriiiing part of Letters Patent No. 661,875, dated November 13, 1900.

Application iiled January 10, 1900. Serial No. 1,005- (No model To all whom it may concern:

Be it known th at I, SALOMON SAMUEL HUR WITZ, a subject of the Emperor of Russia, residing at Dresden A, Saxony, Germany, have invented certain new and useful Improvements in or Relating to Machines for Preparing Cigarette-Papers, (for which I have applied i'or Letters Pat-ent in Germany, dated June 12, i899, H. 22,260, III/79,) of which the following is a specification.

The present invention relates to amachine for covering cigarette mouthpieces or papers with gold, silver, aluminium, or other meallic leaf or the "like in connection with the manufacture of cigarettes or cigarette-shells, the continuous paper strip from a roll being covered in the required places. The further work in connection with the strip after being gilded or covered in the required parts with leaf metal or the like, as produced according to this invention, can be carried ont in various ways. Such work will, however, not be described here, as they do not form part of the invention. One way of connecting the present machine or apparatus with a cigarettemaking machinesay in the case of machines of the Bonsack or Elliott type, in which an endless rope of tobacco is employed-would be to inclose the tobacco rope with paper tubing covered by means of t-his machine, the rope being afterward cut into separate cigarettes. In connection with such a process of manufacture it is a special advantage in favor of Ycovered with some adhesive material in the desired places. On the same side of the paper strip a metallic leaf strip supported by a strong paper strip is passed in such a manner over cylinders that the said paper strip and metal-foil strip face each other at the places to be covered. For this purpose a pressing device is provided consisting of a base-plate and pressure-plate, between which the two strips are pressed together when the sized part of the paper-shell strip is opposite to the foil strip. In all cases the foil is carried forward by the apparatus to an extent equal to the length of the strip of foil that hasbeen used. With regard to the paperstrip, however, the latter may be moved either periodically from one sized part to the next, in which case the pressing device does not change its place relatively to the machine, or the paper strip may travel on continually, in which case the pressing device, together with the foil strip, will have a reciprocating movement, so as to allow when moving in one direction and at the same speed as the paper strip the attachment of the metal foil to the paper to be perfectly carried out. The latter construction of the machine is especially advantageous, since it not only avoids the intermittent movement which is detrimental to so thin and delicate a material as met-al foil, which is liable to be torn when the movements take place, but it permits the machine to be combined with the rope-forming cigarette-machine in such a manner that the paper strip coming from the reel and covered by the machine may be arranged to immediately enter the cigarette-machinel proper. A form of construction of the latter kind will now be described.

In the accompanying drawings, Figure l is a plan of the machine; Fig. 2, an elevation as seen when looking at the machine in the direction of the arrow A, Fig. l. Fig. 3 is a vertical section on the line C D of Fig. l. Fig. 4E is a vertical longitudinalsection on the line E F, Fig. l, in which the upper part of the pressing device is only partially shown. Eig. 5 is an elevation of the machine viewed in the direction of the arrow B, Eig. l. Fig. 6 represents a section of a portion of the metal-foil strip a', with the supporting paper strip Z9 under it, on an enlarged scale. Fig.

7 is a vertical longitudinal section on the line G H, Eig. 8; and Fig. 8 is avertical crosssection on the line I K, Eig. 7.

The paper strip c passes, as represented by the dotted lines, from the reel arranged to the left 'at the top of Fig. i to the apparatus contained between two parallel side walls l.

IOO

The paper stripv passes, first, through a guide device 2, Figs. 1 and 4, and thence under a cylinder 3 over a base-plate 4 of the pressingV device, thence over a guiding-roller 5, and,I

finally, between feeding-rollers to the farther part of the machine.

such a manner that itis limited as regards its lowest positionV by a set-screw '10, while a spring 11 tends to keep it permanently in its lowest position. Below the cylinder 3 is arranged the mechanism employed for apply,y

ing size or adhesive material at certain places to the under side of the strip c. This 'mechanism consists of a trough 12, Fig. 4, intended to hold the vadhesive material, a cylinder 13, immersed therein and driven -bya disk 14, Fig. 2, with a single tooth which gears with the toothed wheel 15, keyed on the axle of the cylinder 13, and a scraper 16. -A cylinder 18, rotating in bearings lon a carrier 17, is-supplied with adhesive material from the cylinder 13 so long as these two cylinders are in contact, owing to the action of va springV is actuated from kan operatingshaft 2-5`b'y means of a series of toothed wheel-gearing, (represented in Fig. 5,) to which-a continuous movement is given. The `movemen-t of the paper strip c is also continuous, the feeding or drawing-off cylinder 6 being'driv-enf-byth'e operating-shaft 25,intermediate shaft 26, (on which the cylinder 22 is also keyed,) bevelwheels 27, shaft 28,and bevel-wheels 29, Figs. 1 and 2. Although the movement of'the paper strip-c is continuons, thetransfer ofthe adhesive Vmaterial to the under side of the strip is only eected when and as long as the part'23 of v thecircumference of the cylinder 24 is in con'- tact with the slip. In this way only a certain part'of the strip 4is g'ummedjthe length of which is -equal to the length of 'the pa-rt 23, while the =portion of the strip between two gummed Yparts remains ungummed. The under cylinder 7 revolves in bearings on a pivoted block 30, Figs. 1 and 4, which is always pressed upward against the cylinder 6 by a spring 31, Figs. 1 and 5.

A slide 34, carrying the base-plate 4 of the pressing device, moves on rollers 33 in `guideslots 32, Figs. 1, 3, and 4. vA brass plate 4a, Fig. 4, is preferably arranged on the upper pressing-'surface for the-purpose of insuring clean work. The slide 34 is movedforward and backward inthe direction of the movey The cylinder 3is car. ried at the endof a vcarrier 9, pivoted at 8 in ment of the strip c by means of a stud 35 engaging in a cam-groove 36 in 4*a roller keyed on the shaft 28, Figs. l, 2, 4, and 5, the forward movement being such as to coincide as regards speed with themovement of thestrip c.

The presser-plate 4 is prolonged transversely to the direction of movement of the paper strip c, as shown at 37, Figs. 1 and 3. On this uplatform are arranged the reel orl cylinder 38, from which issues the strip a h. The strip is represented in Fig. 3 by a dotted line and consists, as represented, in Fig. 6, of an exceedingly thin strip of leaf metal or foil a and. stout paper strip h below. This paper strip passes overthe guide-cylinders 39 and 40, Figs. 1 and 3, belo'wthe cigarette-paper strip cfand over vthe presser-plate 4. VInasmuch as 'the gold-leaf corresponding tothe stri-p c is taken up'by the latter :the 'paper band h continues on fits way empty over'the cylinder 40 and between the two transport or drawing rollers 41 and 42. 0n the vaxle'of 'the vroller 42 is keyed -a wheel 43 `with an india-rubber rim, Figs. 1, 2, and 3, by which the paper strip a b is carried forward to an-eXten't equal to "tle`breadth of the 4strip c whenever the projecting -part 44 of fthecam-di`sk 45, keyed on the shaft 28, Figs. 2and 3, comes in contact with the 'saidsmall lwheel 43. The roller 41 acts as *a Epresser-'cylinder and rotates in `bearings 47, pivotally 'arranged at 46, Fig. 3,

and Yispressed against the roller 42 by springs 48.Y fln'a'sinuchas`theslide 34 is given are-- ciprocating Amovement `the cam-'disk v45 must also take `part in 'the-movement. It is therefore A`arranged 'on the`shaf-t'28'soas to be movabl-e `longitiu'linallythereon, 'but not revoluble, and is connected with the slide vby a'fork lCO IIO

Figs. z1 vand 2,'a'nd `a spring 56 tends to raise it. `On the other-hand, a lever 58,1pivoted on a 'standard 57, Figs. 11, 2,'and 3, presses on the bolt 54 when the vend of said lever is moved Ydownward by `a system o-f levers 59 60 6-1. This happens when the highest surface 62lof vthecam 45 raises the `rod 6l. By'the action of this systemof leversthe part of the under side of the strip c Y-is pressed on the metal Aleafimn'iediatel'y under it, both strips being firmly pressed ltogether between the base-'plate v4-and the Ipresser-plate 55. This part oftheoperation is carried out while the slide is lpassing forward, together with the paper Aband 'd h. When the rod 61 leavesthe s'urf'ace 62, the presser-plate'55 wil-1 -loe raised and the strip c will no'wpassonwith the metallic leaf firmly gummed to it, while vthe slide 34 returns andthe foil stripe; b is' drawn forward toan extent equal to the length of the istrip of -Afoil removedelo'y the band c.

In ord-er'tolobtainaclean separation of the part of the inetalcementedto the baud c from the restof the strip, the followingdevice has been introduced into the mechanism: A sharp-edged blade or knife is made' to press on the edge of the strip c on the strip a b after the presser-plate is raised and while the strip c is on its way forward and the slide 34 on its return movement. Owing to this arrangement the metal portion cemented to the strip c will tear off along the edge of the knife as if cut through. The blade 63, Figs. 3 and 4, is guided in a slot of the presserplate 55 and by means of two pins 64 on the plate 65 is connected with the said presserplate and is pressed downward by springs arranged around the said pins as far as slots providedin the blade, Fig. 4, and small screws 66, passing through the slots, will allow. After the leaf metal has been attached to the strip c by the action of the cam 62 the lower portion 62a of the said cam allows the presserplate 65 to be raised so far that the pressure ceases, although the blade 63 still presses on the strip 0J b. It is only when the cam 62a leaves the rod 6l that the blade is taken off the strip, owing to the presser-plate still receding, and it is only at this moment that the forward movement of the strip d b is started again. 1

I n the second form of construction, in which Fig. 7 represents a vertical longitudinal section on the line G H of Fig. 8 and Fig. 8 a vertical cross-section on the line I K of Fig. 7, the paper strip c is periodically carried forward by the cylinders 6 and 7. By the side of the cylinder 6 is arranged on the same shaft a cam 67, Fig. 7the projecting circumference of which presses against a projection M 68 on a plate 30, whereby the presser-cylinder 7 is pressed back during a certain portion of a revolution, and thereby rendered ineffective as a drawing-roller. Of course the cylinder 6 still continues its movement; but during the time as it is not in contact wit-h the cylinder 7 there will be no friction between the circumferences of the cylinders b' and 7 to carry the paper forward. The bearing 30 is differently arranged, as compared with the first form ot' construction, inasmuch as the spring 3l is connected to the vertical arm 30a of the bearing 30. In this form of Vconstruction the gum-applying cylinder 24 also stops whenever the band cstops, although it may continue to revolve, (in which case the diameter would have to be correspondingly increased,) since it is only the projecting part 23 which is effective during a portion of a complete turn. The periodical stopping is accomplished by a toothed wheel G9, provided with teeth extending entirely around a portion only of its circumference, leaving a portion 7l without teeth, as shown in Fig. 8, said wheel 69 being mounted on the shaft 2b' and gearing intermittently with a toothed wheel 70 on the axle of the pressercylinder, aswill be readily understood. In order, however, to continuously transmit the movement of the operating-shaft 25 to the gumming device, an intermediate wheel 72,

revolving on a stud, is caused to gear with the fully-toothed circumferential part of the wheel 69, which is of double breadth for that purpose, which wheel 72, on the other hand, is drive n. by means of the toothed wheel 73 from the toothed wheel 74 of the operating-shaft. Inasmuch as in this form of construction the presser device vis not intended to move, the hase-plate 4, with its prolongations 37, is iiX- edly arranged in the machine. Accordingly the cam 45a, with the projecting circumferential part 44, is tixedly keyed on the shaft 28, as well as the cam-disk 45h, Fig. 7, carrying the stepped cam 62 52, Fig. 8, for actuating the presser-plate 65. The said presserplate is actuated in this case by means of a pivoted lever 58, the center 58b of which is arranged in bearings in two standards 57a. To the outer ends of the lever-arms are connected rods 75, the slotted ends 76 of which embrace theshaft 28, Fig. 8, and are connected by a crosspiece 77, provided with small rollers 78, by means of which the latter is pressed against thel cam G2 62".
